Send almost any token from any chain. It lands in your vault as dollars.
Stack buys Bitcoin, Ether or NEAR for you every week, skips the weeks when fees run high, and sends the coins to your own wallet.
No wallet or money needed for the demo. Signing in only asks your wallet to sign a message.
Send almost any token from any chain. It lands in your vault as dollars.
Pick the coin, the amount, how often, your own address and the most you'll pay in fees.
Each week your vault buys and the coins arrive in your wallet. Expensive weeks are skipped.
Within your 3% limit: this buy goes ahead.
Bitcoin's network charges about $1.50 to deliver each buy, so buys under $55 cost more than 3%. Estimates from real quotes; every real buy is checked against a live one.
Your dollars sit in a vault
only you can empty. Each buy is capped by the vault's own rules≤ $100 a week. Pause any time, and the coins land in your own wallet
.
These limits are written into your vault's contract on NEAR, not kept as a promise on a server. Each one has a test you can run.
Read the vault's rules


Only start a buy your vault allows: at most one per period, never more than your amount, delivered to the address you set. It can't withdraw, change your plan or change where coins go. If its key were ever stolen, the most it could misdirect is one buy per period until you press Pause.
Fees are everything between the dollars you spend and the coins you get: the swap spread and the network's delivery charge. Before every buy Stack gets a live quote. If its fees are above your limit, that week is skipped and nothing is spent.
USDC, USDT, SOL, ETH and most other tokens on the chains NEAR Intents supports. Whatever you send arrives in your vault as US dollars (USDC on NEAR), ready for your next buys.
Yes, at any time, with one transaction from your own wallet. Withdrawing is always open, even while a plan is running, and only you can do it.
Nothing on top. You pay the swap and network fees shown before each buy, and a little NEAR for the transactions you sign yourself.
The button opens a private example vault with four weeks of history. No wallet, no money, nothing to install.
Every week, about 1.75% in fees, so $5,200 a year into Bitcoin.
